6 Claims.

This invention relates to improvements in container closures and the method of making the same.

More specifically, the present invention is directed to what is known in the trade as metal tie strip for closing containers such as paper bags and the like, wherein a metal strip enclosed in paper is permanently attached to one wall of a container-at or near the closing end thereof. This tie strip of the present invention is made up of three diiierent parts; namely, a metal strip, a covering for the metal strip, and an1 attaching flap secured to the covered metal s r p.

The customary metal tie strips with attaching "flaps now used consist of two parts; a, narrow metal strip and a comparatively wide paper covering strip. The metal strip is enclosed in one edge of a covering strip; the other edge, projecting some distancefrom the covered metal part, is used as an attaching flap; but in order to make a practical structure, sections of this projecting covering material must be cut away, thus wasting a considerable amount of material.

it is further pointed out that in the old method the whole covering material is the same as required for the stronger attaching part of the metal closure strip.

Objects of the present invention are the provision of a bag tie wherein the three-part tie strip offers simplified manufacture, eliminating dying out and saving of material. We do not desire to be limited to a non-metallic covering strip as there are some paper reinforced metallic materials that may be used as a covering strip.

Other objects oi? the present invention will be manifest from the following description and the accompanying drawings, in which drawings:

Fig. 1 is a perspective View of a bag embodying our improved structure; Fig. 2 is a vertical sectional view of the same; Fig. 3 is a perspective view of another form of bag embodying our invention; and

Fig. 4 is a vertical sectional view of the same. Referring to the drawings in detail: 2 designates a container made of paper or other suitable 'material, the closure end of which is provided with our improved tie. It is to be understood that while we have illustrated a single ply bag in the drawings, we do not wish to be limited to this application of our invention as, obviously, the same can be applied to multi-ply bags, envelopes, wrappers, etc. wherein it is required to close one end.

1938, ScrialNo. 194,815 (01. 229-65) The bag 2 is of the type wherein the rear wall extends beyond the end of the opposite wall of the bag to form a'projecting flap 4.

To the-face oi the back wall of the bag we adhesively secure a non-metallic attaching strip 5, which may be of paper or other suitable material. This attaching strip 6, it will be noted, extends beyond-the end of the flap 4, and inasmuch as it isno wider'than the bag wall, the necessity of dying out is eliminated, thereby not only effecting a saving in both material and labor but adapting our construction to continuous-motion manufacture.

To the attaching strip 6 we adhesively secure or fasten another strip 8. This strip 8 is wider than the bag, in fact its width is equal to the length of the metal strip Ill of the tie.

The attaching strip 5 and covering strip 8 are shown folded around the metal tie strip l0, as shown in Fig. 2, so that the front face of the metal tie strip is adhesively secured to the attaching strip 6 and its rear face to the covering strip 8. As an alternative to this construction the attaching strip 6 may not enclose the metal tie strip, but may be terminated at any point above the lower edge of the covering strip 8,

The attaching strip 6 is of a strong material, its primary function being to provide a stron attachment of the tie to the bag. While the material of this strip is strong, a saving in material cost is efiected by employing a strip no wider than the bag wall thus eliminatingdying out and consequent waste, our construction possessing the further advantage, already pointed out, of lending itself to continuousmotion manui'acture. The material 8 may be any cheap grade of material in that its function is merely to cover the strip Hi.

When the container is filled and it is desired to close the end of the bag the tie is folded or rolled over with the opposite end wall as many times as desired and the projecting endsell fold ed transversely of the front wall of the bag.

Referring to the embodiment of the invention illustrated in Figs. 3 and 4: 22 designates the bag. This bag has no projecting flap at its open end.

Secured to the rear wall of this bag is an attaching strip 26 similar to the attaching strip 6 of Fig. 1 and to the outside of the attaching strip 25 is secured a covering strip 28' similar to the covering strip 8 of Fig. 1. The metallic tie strip of this tie is designated 20 and is similar to the strip ill of Fig. '1. The

strips

26 and 28 may be folded around the tie strip in a fashion similar to that described in connection with Fig.1, or the attaching strip maybe terminated short of the upper edge of the tie strip instead of being folded about it. The attaching strip 26 is no wider than the bag wall so that the same advantages are efi'ected as pointed out in connection with Figs. 1 and 2.

It will be appreciated thatin both forms of our invention herein illustrated and described the attaching strip provides for a very much improved attachment of the tie to the bag as compared with prior structures. i

It is to be understood that various changes and modifications may be made in the structures herein illustrated and described without departing from the spirit and scope of our invention.

What we claim is:

1. In combination a container having a projecting flap at its open end, an attaching strip tobe secured to the container Wall and to said flap, a metallic tie strip, and a cover for said tie strip, one face of said metallic tie strip being adhesively secured to said attaching strip, the

opposite face being secured to the cover strip.

2. In combination an attaching strip to be applied to the outer face of one wall of a container and projecting beyond the end of the container, said attaching strip'being of a width not greater than the width of the container wall, a covering strip secured to said attaching strip,

a metallic tie strip, said attaching strip and said 'covering strip being wrapped about the metallic tie strip so that one face of the tie strip may be adhesively secured to the attaching strip and the other face adhesively secured to the covering strip.

3. The method of making closures for containers which comprises applying an attaching strip to the end of a container with a portion of the attaching strip extending beyond the end of the container, adhesively securing a cover strip to said attaching strip with the cover strip extending beyond the attaching strip and folding the two strips about a metal tie member and adhesively securing the tie member between the projecting ends-of said strips 4. An article of manufacture comprising a metallic tie strip. a covering strip, and an attaching strip, the latter being separate from but secured to the metallic' tie strip and the covering strip, the metallic tie strip projecting beyond the sides of the attaching strip.

5. An article of manufacture comprising a metallic tie strip, a covering strip wrapped about the tie strip, an attaching strip separate from but secured to said covering strip, the tie strip being greater in length than the width of the attaching strip so that the tie strip projects beyond the sides of the attaching strip.

6. As an article of manufacture, a covered metal tying strip for closing a container, said tying strip including an attaching strip to be applied to the wall of the container, the width of the attaching strip being less than the length of the tying strip, the covering for the tying ADOLPH POTDEVIN.
